The canopy effect describes vertical variation in the isotope ratios of carbon (δ13C), oxygen (δ18O) and partially nitrogen (δ15N) within plants throughout a closed canopy forest, and may facilitate the study of canopy feeding niches in arboreal p

The roots of human hunting and meat eating lie deep in our evolutionary past shared with chimpanzees (Pan troglodytes). From the few habituated wild populations, we know that there is considerable variation in the extent to which chimpanzees consume

Who is who matters-The effects of pseudoreplication in stable isotope analyses

Autor: Roger Mundry, Viktoria M. Oelze

Publikováno v: American Journal of Primatology. 78:1017-1030

Stable isotope analysis in free-ranging primates is a promising new avenue in reconstructing feeding niches and temporal dietary variation. Particularly, the large sample sizes obtained from non-invasively collected hair and fecal samples from nests

Previous observations have noted that in some species of higher termites the soldier caste lacks pigmented particles in its gut and, instead, is fed worker saliva that imparts a whitish coloration to the abdomen. In order to investigate the occurrenc
